Airbus Helicopters H155 vs Leonardo Aw139 vs Leonardo Aw169 vs Sikorsky S 76d

In category, the Airbus Helicopters H155 and Sikorsky S‑76D are typically positioned as medium twin, corporate/offshore-class helicopters with a strong emphasis on cabin comfort and efficiency. The Leonardo AW139 sits a step up as a larger medium twin, widely used for offshore transport, EMS, and utility missions where higher payload and cabin volume matter. The Leonardo AW169 is generally the “light-intermediate” twin in this group, bridging lighter twins and full medium platforms with modern avionics and flexible interiors. On range, the AW139 and S‑76D are commonly regarded as the longer-legged options in typical configurations, often chosen for missions requiring more reach or reserves. The H155 is also range-competitive for corporate and offshore profiles, while the AW169 is usually somewhat shorter-range than the AW139 and S‑76D, though still capable for regional and multi-role operations. On passenger capacity, the AW139 generally leads, often configured around the low-to-mid teens depending on layout. The H155 and S‑76D commonly seat around the high single digits to low teens. The AW169 typically carries fewer than the AW139 but can be configured near the H155/S‑76D range depending on mission fit.
